The vacuum furnace comprises a cooling chamber, a heating chamber and separation walls, wherein each separation wall is provided with a heat insulation door; the cooling chamber comprises an air quenching chamber and an oil quenching chamber, the upper part of the air quenching chamber is provided with an air charging quick-cooling mechanism, and the lower part of the oil quenching chamber is provided with an oil quenching oil tank provided with a stirrer; the heating chamber is provided with a gas convection circulation mechanism; the heating chamber and each heat insulation door are respectively sequentially provided with a heat insulation layer, a vacuum layer and a stainless steel shell from inside to outside; and the vacuum furnace also comprises an operation-monitoring system, a dust collector and an exhaust purifier. The vacuum furnace has the advantages of safe oil quenching, uniform material heating, favorable heat insulation effect and high product quality, can observe the machining condition, can prevent the vacuumizer from being corroded, and is environment-friendly in evacuation.

Description

technical field [0001] The invention relates to an observation and monitoring operation vacuum furnace for cleaning the blowdown liquid of an anti-corrosion vacuum pumping machine, and belongs to the technical field of vacuum furnaces. Background technique [0002] At present, the existing vacuum furnace includes a cooling chamber and a heating chamber, and the cooling chamber and the heating chamber are separated by a partition wall; a gas quenching chamber and an oil quenching chamber are arranged inside the cooling chamber, and the gas quenching chamber is provided with an air-filled quick-cooling mechanism. source, while the oil quenching chamber performs oil quenching through the oil quenching tank. The inside of the heating chamber includes a heating chamber platform and a material frame. The material frame is placed on the heating chamber platform. At the same time, one or more heating tubes are evenly arranged in the heating chamber along the circumferential directio...

AI Technical Summary

Problems solved by technology

[0003] 1. During oil quenching, because the processed materials are put into the oil quenching oil tank, the oil surface is heated unevenly and the oil splashes, so accidents are prone to occur

[0004] 2. The inside of the heating chamber is statically heated by the heating tube, so it is easy to cause the material to be heated unevenly, and a good processing effect cannot be achieved.

[0005] 3. The heat insulation effect of the furnace wall of the heating chamber of this design is not good, and the temperature between the cooling chamber and the heating chamber cannot achieve good heat insulation, so the heat dissipation is serious and the energy consumption is high

[0006] 4. When processing materials, this kind of heating furnace can only be processed manually, so its labor cost is high. At the same time, due to the limitation of workers' skills, the various processes cannot be well connected during processing, resulting in processing There are many defective products after the material

[0007] 5. When the existing vacuum furnace is evacuated, a large amount of dust will be generated when the materials in the cooling chamber and the heating chamber are heated or cooled, so when the vacuuming mechanism is evacuated, it is easy to corrode the vacuuming mechanism

[0008] 6. Due to the existing vacuum furnace, when the material is heated in the heating chamber or cooled in the cooling chamber, a large amount of smoke and dust will be generated, and these gases containing a large amount of smoke and dust will be directly discharged into the air, polluting the environment, so it is not environmentally friendly

[0009] 7. This kind of vacuum furnace cannot observe the processing of the workpiece in the heating chamber at any time, so when it processes defective products, it is not easy to distinguish which link in the processing is wrong, so it is inconvenient
